So from all the hints I'm seeing, I might like this new Nexus or Droid Prime or whatever they want to call it. I am a newb at it though, can someone tell me what the Nexus line of phones is all about? Do they really have stock android OS, no manufacturer skins? What makes the previous Nexus phones different from everything else android? Please fill me in, or point me in the right direction. For reference, I'm just on a Samsung continuum now, a basic Android phone for anyone that doesn't know.
